the battery in a ivi'iil-'kiiovifii iiit ii?, 'the sani@ heilig suihczieiit mi ignite-i iiiiiiiiiiiiie @uiting will be oliviiiicd, und this ilsiiiihie iii 'feature is further insured by reason of the fact that the only non-insulated or ex osed portion of the circuit connected witi the member 11 consists ofthe sprin(r 25 and point 26, and this portion is not only normally out of contact with the member 1() but is prevented by said member l() and parts connected therewith from coming into contact with outside'metallic bodies which might cause short-circuiting- As indicated most plainly in Fig. 3, the end 18 is comparative y broad and the edge 19 thereof is long. rThe contact Q6 moves in a plane coincident with the plane in which f the member 11 is pivoted to move, and such 'plane intersects the said edge 1). It will be appreciated, therefore, that the end 18, in addition to the primar function of being a contact, serves to shieh the movable Contact from danger of short-circuiting and being broad would allow of considerable possible distortion of the contact 26 Without likelihood of failure to make contact therewith in the operation of the igniter.

I am aware that it is not broadly new with me to provide a hand igniter for the general purposes for which mine is designed, but if hat I claim as of my invention, and desire to secure by Letters Patent of the United States, is:

1. An electric igniter comprising, in combination, a member substantially semi-circular in cross-section and having its end flat-v tened and bent back parallel with the main portion thereof, said end constituting a stationary contact, a member substantially tu- .bular in cross-section pivoted to and norand circuit wires attached to the contact' members and passing through the said handleS.

2. In an electric igniter, the combination of two contact members pivoted together intermediate of their ends, one of said members carrying a movable spring contact which contact projects in substantial alinement therewith and moves in a plane coincident with the plane of movement of said carr ing member, the other of said contact mem rs having a iiattened end adapted to substantially guard the movable contact from outside infiuence and constituting a stationary contact, operating handles secured to the ends of the said contact members, circuit wires secured to the said lcontact members within the said handles, and sprin means normally tending to retain the mova' le contact within the stationary contact, substantially as set forth.

In testimony whereof I affix my signature in presence oftwo witnesses.
